A randomized controlled trial of multi-session online interpretation bias modification training: Short- and long-term effects on anxiety and depression in unselected adolescents

Towards implementation of cognitive bias modification in mental health care: State of the science, best practices, and ways forward

Cognitive bias modification (CBM) has evolved from an experimental method testing cognitive mechanisms of psychopathology to a promising tool for accessible digital mental health care. While we are still discovering the conditions under which clinically relevant effects occur, the dire need for accessible, effective, and low-cost mental health tools underscores the need for implementation where such tools are available. Providing our expert opinion as Association for Cognitive Bias Modification members, we first discuss the readiness of different CBM approaches for clinical implementation, then discuss key considerations with regard to implementation. Evidence is robust for approach bias modification as an adjunctive intervention for alcohol use disorders and interpretation bias modification as a stand-alone intervention for anxiety disorders. Theoretical predictions regarding the mechanisms by which bias and symptom change occur await further testing. We propose that CBM interventions with demonstrated efficacy should be provided to the targeted populations. To facilitate this, we set a research agenda based on implementation frameworks, which includes feasibility and acceptability testing, co-creation with end-users, and collaboration with industry partners.

Codesigned online cognitive bias modification of interpretations for anxiety and depression in children: study protocol of a randomised controlled trial

INTRODUCTION

Previous research has shown that cognitive bias modification of interpretations (CBM-I) may be a promising intervention for anxiety in youth; however, results are mixed. Given the high comorbidity between anxiety and depression in youth, it is surprising that no child studies have targeted biases associated with both. This study aims to evaluate the effectiveness and acceptability of an online CBM-I intervention (Mindmaster) for children with symptom scores of anxiety or depression above a borderline or clinical threshold. The intervention has been codesigned with children, parents and mental health professionals to promote user engagement.

METHODS AND ANALYSIS

The study is a randomised controlled trial, with two parallel arms. Participants are 143 children aged 8-10 years with scores of anxiety and/or depressive symptoms above a borderline or clinical threshold. They will be allocated to either the intervention group or the waitlist control group. The intervention consists of 2 weeks of online CBM-I training, with four sessions (10-15 min) per week. Outcome assessments will be conducted at baseline, 4 weeks after baseline (post-training/post-waitlist) and 8 weeks after baseline (follow-up) for the intervention group only. The primary outcome is interpretation bias. Secondary outcomes are anxiety and depressive symptoms and life interference. Analyses will be conducted within an intention-to-treat framework using mixed models for repeated measures.

ETHICS AND DISSEMINATION

The study was approved by the University of New South Wales Human Research Ethics Committee (HC220758). Findings will be reported to (1) participating families; (2) presented at scientific conferences and (3) disseminated to peer-review publications. Data will be available from the corresponding author on request.

Cognitive bias modification of interpretations for anxiety and depression in children and adolescents: A meta-analysis

Background

Evidence suggests that cognitive bias modification of interpretations (CBM-I) is effective in modifying interpretation biases and has a small effect on reducing anxiety in children and adolescents. However, most evidence to date is based on studies which report anxiety or general distress using ad-hoc Likert-type or Visual Analogue Scales, which are useful but do not reliably index symptoms of clinical importance. This meta-analysis aimed to establish the effects of CBM-I for children and adolescents on both anxiety and depression using psychometrically validated symptom measures, as well as state negative affect and negative and positive interpretation bias.

Methods

We identified studies through a systematic search. To be eligible for inclusion, studies needed to target interpretation biases, not combine CBM-I with another intervention, randomly allocate participants to CBM-I or a control condition, assess a mental health outcome (i.e., anxiety or depression symptoms using validated measures or state measures of negative affect) and/or interpretation bias and have a mean age less than 18 years.

Results

We identified 36 studies for inclusion in the meta-analysis. CBM-I had a small and non-significant unadjusted effect on anxiety symptoms (g = 0.16), no effect on depression symptoms (g = -0.03), and small and non-significant unadjusted effects on state negative affect both at post-training (g = 0.16) and following a stressor task (g = 0.23). In line with previous findings, CBM-I had moderate to large unadjusted effects on negative and positive interpretations (g = 0.78 and g = 0.52). No significant moderators were identified.

Conclusions

CBM-I is effective at modifying interpretation bias, however there were no effects on mental health outcomes. The substantial variability across studies and paucity of studies using validated symptom measures highlight the need to establish randomized controlled trial protocols that evaluate CBM-I in clinical youth samples to determine its future as a clinical intervention.

Web-Based Cognitive Bias Modification Program for Young People With Social Anxiety and Hazardous Alcohol Use: Feasibility, Acceptability, and Preliminary Efficacy Study

BACKGROUND

Interpretation bias modification (IBM) and approach bias modification (ApBM) cognitive retraining interventions can be efficacious adjunctive treatments for improving social anxiety and alcohol use problems. However, previous trials have not examined the combination of these interventions in a young, comorbid sample.

OBJECTIVE

This study aims to describe the feasibility, acceptability, and preliminary efficacy of a web-based IBM+ApBM program for young adults with social anxiety and hazardous alcohol use ("Re-Train Your Brain") when delivered in conjunction with treatment as usual (TAU).

METHODS

The study involved a 3-arm randomized controlled pilot trial in which treatment-seeking young adults (aged 18-30 y) with co-occurring social anxiety and hazardous alcohol use were randomized to receive (1) the "integrated" Re-Train Your Brain program, where each session included both IBM and ApBM (50:50 ratio), plus TAU (35/100, 35%); (2) the "alternating" Re-Train Your Brain program, where each session focused on IBM or ApBM in an alternating pattern, plus TAU (32/100, 32%); or (3) TAU only (33/100, 33%). Primary outcomes included feasibility and acceptability, and secondary efficacy outcomes included changes in cognitive biases, social anxiety symptoms, and alcohol use. Assessments were conducted at baseline, after the intervention period (6 weeks after baseline), and 12 weeks after baseline.

RESULTS

Both Re-Train Your Brain program formats were feasible and acceptable for young adults. When coupled with TAU, both integrated and alternating programs resulted in greater self-reported improvements than TAU only in anxiety interpretation biases (at the 6-week follow-up; Cohen d=0.80 and Cohen d=0.89) and comorbid interpretation biases (at the 12-week follow-up; Cohen d=1.53 and Cohen d=1.67). In addition, the alternating group reported larger improvements over the control group in generalized social anxiety symptoms (at the 12-week follow-up; Cohen d=0.83) and alcohol cravings (at the 6-week follow-up; Cohen d=0.81). There were null effects on all other variables and no differences between the intervention groups in efficacy outcomes.

CONCLUSIONS

Should these findings be replicated in a larger randomized controlled trial, Re-Train Your Brain has the potential to be a scalable, low-cost, and non-labor-intensive adjunct intervention for targeting interpretation and comorbidity biases as well as generalized anxiety and alcohol-related outcomes in the real world.

Study protocol for a randomized controlled trial investigating the effect of online interpretation bias intervention on stress reactivity in the children of parents with depression: the CoCo study

BACKGROUND

Current preventive interventions for the children of parents with depression demonstrate modest effects on depression incidence. This may be because existing interventions tend to comprise general psychotherapeutic tools, rather than targeting the specific mechanisms underlying familial transmission. Improved theoretical models of familial transmission could enhance the development of targeted interventions. Although existing models assume that cognitive and biological vulnerability factors influence one another, the precise mechanisms are unknown. This project is the first to experimentally test whether negative interpretation bias has an impact on cortisol response in children of parents with depression. This study protocol reports a randomised controlled trial of an interpretation bias intervention which aims to shift participants' interpretation bias in a more positive direction and thereby alter their stress response.

METHODS

Children aged 10-14 years who have i) one parent with a current or previous depression diagnosis, with at least one episode occurring during the child's lifetime and ii) do not have a current or previous psychiatric diagnosis themselves, will be assigned to one of two conditions: an interpretation bias intervention (n = 50) or a structurally similar placebo intervention (n = 50). The interpretation bias intervention consists of a short lab-based cognitive reappraisal of interpretations training, a four-week app-based Cognitive Bias Modification of Interpretations intervention and interpretation bias specific if-then plans. Interpretation bias will be assessed before and after the intervention using the Scrambled Sentences Task. The effect of the intervention on participants' stress response will be assessed by salivary cortisol collected at five different time points: from immediately before until 45 min after administering the Trier Social Stressor Test for Children. Stress reactivity will be measured via baseline to peak cortisol and stress recovery will be measured via the 45 min cortisol marker. We hypothesise that children who participate in the interpretation bias intervention will display a positive shift in interpretation bias and this, in turn, will alter their stress response. Children who receive the placebo intervention are expected to show a smaller positive shift in interpretation bias and stress reactivity.

DISCUSSION

The findings of the present study will contribute to models of familial depression transmission as well as informing preventive interventions. If training a more positive interpretation bias subsequently alters participants' stress response, then incorporating such tools may increase the efficacy of existing preventive interventions.

A double-blind phase II randomized controlled trial of an online cognitive bias modification for interpretation program with and without psychoeducation for people with chronic pain

ABSTRACT

Cognitive bias modification for interpretation (CBM-I) is an effective intervention for anxiety, but there is only a single trial in people with chronic pain. The aim of this randomized controlled trial was to test CBM-I with and without psychoeducation for people with chronic pain. We randomized 288 participants to 4 groups comprising treatment (CBM-I vs placebo) with or without psychoeducation. One hundred and eighty-three participants (64%) completed 4, 15-minute training sessions over 2 weeks. The coprimary outcomes were pain interference and pain intensity. We also measured interpretation bias, fear of movement, catastrophizing, depression, anxiety, and stress. Participants with more psychopathology at baseline were more likely to dropout, as were those allocated to psychoeducation. Intention-to-treat analyses using linear mixed models regression were conducted. Training effects of CBM-I were found on interpretation bias, but not a near-transfer task. Cognitive bias modification of interpretation improved both primary outcomes compared with placebo. For pain interference, there was also a main effect favoring psychoeducation. The CBM-I group improved significantly more than placebo for fear of movement, but not catastrophizing, depression, or anxiety. Cognitive bias modification of interpretation reduced stress but only for those who also received psychoeducation. This trial shows that CBM-I has promise in the management of pain, but there was limited evidence that psychoeducation improved the efficacy of CBM-I. Cognitive bias modification of interpretation was administered entirely remotely and is highly scalable, but future research should focus on paradigms that lead to better engagement of people with chronic pain with CBM-I.

Effectiveness of Online Interventions for the Universal and Selective Prevention of Mental Health Problems Among Adolescents: a Systematic Review and Meta-Analysis

With the emergence of the coronavirus disease 2019 pandemic as a threat to mental health, the demand for online interventions that can replace face-to-face approaches for the prevention of mental health problems is increasing. Although several previous reviews on online interventions have targeted adolescents with symptoms of or those diagnosed with mental illness, there is still a lack of evidence on the effectiveness of online preventive interventions for general and at-risk adolescents. Therefore, this review aimed to evaluate the effectiveness of online interventions on the prevention of an increase in the scores of stress, anxiety, and depression in general and at-risk adolescents. A search was performed using PubMed, EMBASE, and Cochrane Library CENTRAL. Altogether, 19 studies were included, and 16 studies were used for the meta-analysis. Our results showed that cognitive behavioral therapy and family-based interventions were most commonly used. Twelve and seven studies conducted universal and selective preventive interventions, respectively. The meta-analysis showed that online interventions significantly prevent an increase in depression score but not in stress and anxiety scores. Evidence regarding the prevention of increases in stress and anxiety scores is limited, suggesting the need for further randomized controlled trials on online interventions for stress and anxiety in adolescents.

The combined cognitive bias hypothesis in anxiety: A systematic review and meta-analysis

Cognitive theories have postulated the relational nature of different cognitive biases in the development and maintenance of anxiety disorders. To test this combined cognitive bias hypothesis, this review addressed the following questions: (i) whether different cognitive biases are associated with each other and (ii) whether one bias influences another bias. We identified 36 articles that studied the relationship between cognitive biases (attention, interpretation and memory bias). Of these, 31 studies were entered into two meta-analyses. Sixteen studies were included in the first meta-analysis of the correlation between cognitive bias indices. A further 15 studies were included in another meta-analysis to examine the transfer effects of cognitive bias modification (CBM) to another bias. Both meta-analyses yielded small but significant overall pooled effect sizes after the removal of outliers (r = 0.11 and g = 0.19 respectively). Moderator analyses revealed that the relationship between interpretation and memory bias was significantly stronger than other types of cognitive bias correlations and CBM is more potent in modifying biases when it was delivered in the laboratory compared with online. Our review quantifies the strength of the relationships between biases and transfer effects following CBM, which serves as a basis to further understand the mechanisms underlying biased information processing.

Development of a Brief Group CBT Intervention to Reduce COVID-19 Related Distress Among School-Age Youth

School-aged youth have been significantly impacted by the COVID-19 pandemic. The effects of the pandemic will likely have long-standing effects on the well-being of youth, and access to mental health care is even more critical during this time. For the past 5 years, TRAILS (Transforming Research into Action to Improve the Lives of Students) has been working throughout the state to increase utilization of evidence-based mental health practices among K-12 school mental health professionals (SMHPs). By leveraging SMHPs who are widely accessible to students, TRAILS seeks to improve youth access to effective mental health care and reduce current mental health inequities. In March 2020, TRAILS responded to the COVID-19 pandemic by developing a group manual designed to be delivered virtually by SMHPs to help students develop effective coping skills to mitigate the impact of COVID-19. TRAILS focuses on promoting use of CBT and mindfulness, as these skills are ideally suited for school-based delivery, and thus the new manual, Coping with COVID-19 (CC-19), was grounded in these modalities. This article will describe the design, development, and deployment of the CC-19 program to address the mental health needs of students in the context of the pandemic. Early acceptability and penetration data will also be discussed.

Disentangling the mediating role of modifying interpretation bias on emotional distress using a novel cognitive bias modification program

BACKGROUND

Negative interpretation bias is a potential risk factor for emotional disorders. In this study, we tested a clinically inspired 4-session online Cognitive Bias Modification-Interpretation (CBM-I_Clin) program to modify negative interpretation biases.

METHODS

We randomized one hundred and twenty-one volunteer young adults (Mean age = 21.6 years, SD = 3.5; 85 % women) with varying levels of emotional distress to either an experimental or waitlist control group. Mediation analyses were used to disentangle the associations between the intervention, changes in interpretation biases (assessed by both a self-report and an experimental task), and changes in measures of cognitive vulnerability and symptoms of depression and anxiety.

RESULTS

The results showed that the CBM-I_Clin could change negative interpretation biases. Also, it had a direct effect on the change in negative memory bias, an indirect effect on the change in depression symptoms via the change in interpretation bias, and both direct and indirect effects on the change in self-reported dysfunctional attitudes.

LIMITATIONS

The study included a non-clinical sample of participants and it did not control for some potential confounding factors (e.g., attentional disorders). Furthermore, participants' engagement during the sessions at home was not supervised.

CONCLUSIONS

The CBM-I_Clin is a potential tool to prevent and intervene in emotional disorders in young adults and could complement other traditional CBM procedures or clinical interventions.

Promoting helpful attention and interpretation patterns to reduce anxiety and depression in young people: weaving scientific data with young peoples' lived experiences

BACKGROUND

Anxiety and depression are common, disabling and frequently start in youth, underscoring the need for effective, accessible early interventions. Empirical data and consultations with lived experience youth representatives suggest that maladaptive cognitive patterns contribute to and maintain anxiety and depression in daily life. Promoting adaptive cognitive patterns could therefore reflect "active ingredients" in the treatment and/or prevention of youth anxiety and depression. Here, we described and compared different therapeutic techniques that equipped young people with a more flexible capacity to use attention and/or promoted a tendency to positive/benign (over threatening/negative) interpretations of uncertain situations.

METHODS

We searched electronic databases (PubMed, PsycINFO, EMBASE, and PsycARTICLES) for studies containing words relating to: intervention; youth; anxiety and/or depression and attention and/or interpretation, and selected studies which sought to reduce self-reported anxiety/depression in youth by explicitly altering attention and/or interpretation patterns. Ten young people with lived experiences of anxiety and depression and from diverse backgrounds were consulted on the relevance of these strategies in managing emotions in their daily lives and also whether there were additional strategies that could be targeted to promote adaptive thinking styles.

RESULTS

Two sets of techniques, each targeting different levels of responding with different strengths and weaknesses were identified. Cognitive bias modification training (CBM) tasks were largely able to alter attention and interpretation biases but the effects of training on clinical symptoms was more mixed. In contrast, guided instructions that teach young people to regulate their attention or to evaluate alternative explanations of personally-salient events, reduced symptoms but there was little experimental data establishing the intervention mechanism. Lived experience representatives suggested that strategies such as deliberately recalling positive past experiences or positive aspects of oneself to counteract negative thinking.

DISCUSSION

CBM techniques target clear hypothesised mechanisms but require further co-design with young people to make them more engaging and augment their clinical effects. Guided instructions benefit from being embedded in clinical interventions, but lack empirical data to support their intervention mechanism, underscoring the need for more experimental work. Feedback from young people suggest that combining complimentary techniques within multi-pronged "toolboxes" to develop resilient thinking patterns in youth is empowering.

A Systematic Review on TeleMental Health in Youth Mental Health: Focus on Anxiety, Depression and Obsessive-Compulsive Disorder

Background and Objectives: The Internet is widely used and disseminated amongst youngsters and many web-based applications may serve to improve mental health care access, particularly in remote and distant sites or in settings where there is a shortage of mental health practitioners. However, in recent years, specific digital psychiatry interventions have been developed and implemented for special populations such as children and adolescents. Materials and Methods: Hereby, we describe the current state-of-the-art in the field of TMH application for young mental health, focusing on recent studies concerning anxiety, obsessive-compulsive disorder and affective disorders. Results: After screening and selection process, a total of 56 studies focusing on TMH applied to youth depression (n = 29), to only youth anxiety (n = 12) or mixed youth anxiety/depression (n = 7) and youth OCD (n = 8) were selected and retrieved. Conclusions: Telemental Health (TMH; i.e., the use of telecommunications and information technology to provide access to mental health assessment, diagnosis, intervention, consultation, supervision across distance) may offer an effective and efficacious tool to overcome many of the barriers encountering in the delivery of young mental health care.

Characteristics of effective online interventions: implications for adolescents with personality disorder during a global pandemic

In recent years, the necessity of providing online interventions for adolescents, as an alternative to face-to-face interventions, has become apparent due to several barriers some adolescents face in accessing treatment. This need has become more critical with the coronavirus disease 2019 (COVID-19) global pandemic impacting the delivery of psychotherapy and limiting accessibility of face-to-face therapy. Whilst it has been established that face-to-face psychotherapy for adolescents with personality disorder can be effective in reducing the impact these complex mental illnesses have on functioning, online interventions for adolescents are rare, and to our knowledge there are no empirically validated online interventions for personality disorder. The development of novel online interventions are therefore necessary. To inform the development of online interventions for adolescents with personality disorder or symptoms of emerging personality disorder, a two-phase rapid review was conducted. Phase one consisted of a search and examination of existing online mental health programs for adolescents with symptoms of personality disorder, to understand how to best use online platforms. Phase two consisted of a rapid review of empirical literature examining online interventions for adolescents experiencing symptoms of personality disorder to identify characteristics that promote efficacy. There were no online programs specific to personality disorder in adolescence. However, 32 online mental health programs and 41 published empirical studies were included for analysis. Common intervention characteristics included timeframes of one to two months, regular confidential therapist contact, simple interactive online components and modules, and the inclusion of homework or workbook activities to practice new skills. There is an urgent need for online interventions targeting personality dysfunction in adolescence. Several characteristics of effective online interventions for adolescents were identified. These characteristics can help inform the development and implementation of novel online treatments to prevent and reduce the burden and impact of personality disorder, or symptoms of emerging personality disorder, in adolescents. This has implications for the COVID-19 pandemic when access to effective online interventions has become more urgent.

Moderators of psychological and psychoeducational interventions for the prevention of anxiety: A systematic review

The aim of this study was to assess the available evidence on potential moderators of psychological and psychoeducational interventions for the prevention of anxiety. A systematic review using PubMed, PsycINFO, Web of Science, Embase, OpenGrey, and CENTRAL was performed up to October 2019. Two independent researchers assessed the fulfillment of eligibility criteria, extracted the data and performed a quality assessment of the included studies. Outcomes were moderators of the reduction of anxious symptoms or the incidence of anxiety disorders. Fourteen studies reporting results on moderator analyses performed in 13 randomized controlled trials were included. Twenty-seven potential moderators were organized into six categories: sociodemographic, clinical characteristics, cognitive variables, life events, interpersonal functioning and intervention characteristics. The most frequently examined variables were gender, age and baseline anxiety. We found insufficient evidence for all moderator categories studied. In children and adolescents, we found some studies with significant results for the low family support variable and higher levels of anxiety symptoms at baseline, which were both associated with higher effectiveness. Limited conclusions can be drawn about for whom and under what conditions interventions work in the prevention of anxiety. A strong need to improve the methodological quality and the number of moderator studies was identified.

Cognitive Bias Modification Reduces Social Anxiety Symptoms in Socially Anxious Adolescents with Mild Intellectual Disabilities: A Randomized Controlled Trial

The goal of this study was to examine the effects of Cognitive Bias Modification training for Interpretation (CBM-I) in socially anxious adolescents with Mild Intellectual Disabilities (MID). A total of 69 socially anxious adolescents with MID were randomly assigned to either a positive or a neutral control-CMB-I-training. Training included five sessions in a 3-week period, and each session consisted of 40 training items. Adolescents in the positive training group showed a significant reduction in negative interpretation bias on the two interpretation bias tasks after training compared to adolescents in the control-training group. Furthermore, in contrast to the control-training group, adolescents in the positive training reported a significant reduction of their social anxiety symptoms 10 weeks post-training.

Emotional working memory training as an online intervention for adolescent anxiety and depression: A randomised controlled trial

Objective

Anxiety and depression are highly prevalent disorders in adolescence. They are associated with deficits in working memory (WM), which also appears to increase rumination, worry, and negative mood. WM training, especially in an emotional context, might help in reducing or preventing these disorders. The current study investigated the direct effects of online emotional WM training on WM capacity, and short‐ and long‐term effects on symptoms of anxiety and depression, and secondary measures of emotional functioning.

Methods

Unselected adolescents (n = 168, aged 11–18) were randomised over an active or placebo emotional WM training. WM was assessed before and after 4 weeks of bi‐weekly training. Emotional functioning was assessed pre‐ and post‐training and at 3, 6, and 12 months follow‐up.

Results

Improvements in WM capacity and both short‐ and long‐term emotional functioning were found in both training groups, with the only group difference being a trend for a larger increase in self‐esteem in the active group compared to the placebo group.

Conclusions

The general improvements irrespective of training condition suggest non‐specific training or time effects, or some shared active ingredient in both conditions. Future research is necessary to detect potentially effective components of (emotional) WM training and to increase adolescent engagement with online training.
